4.3.2
Capacitor trip device for shunt trips
4.3.2.1
Description
In the event of short-time brownouts of the supply voltage, the capacitor trip device
takes over the power supply of the shunt trips for uninterrupted duty, see Chapter
Closing coil, shunt trip, undervoltage release (Page 234).
Note
Only shunt trips with an operational voltage of 220 V to 250 V DC / 208 V to 240 V AC
can be used in combination with the capacitor trip device.
You will find more information in the operating instructions available on the internet
(https://support.industry.siemens.com/cs/ww/en/view/109793919).
